Problems solved by technology

[0003] With the development of ceramic membrane functionality, people found that when the current enters the ceramic membrane (TCM planar resistance membrane), an electrothermal effect will occur, resulting in electrothermal conversion. When a certain temperature is reached, the ceramic membrane will generate a large number of life light waves; therefore, how to Using this characteristic, how to carry out product development and utilization, how to carry out mass production, has a great role in making up for the shortage of far-infrared products in the market and improving the physical fitness of citizens. Therefore, a corresponding production process has been formed in the production. The process also has the problem of low efficiency caused by too large parameter limit range. It is very necessary to further limit the parameters to highlight high production efficiency. For this reason, a TCM component planar circuit diagram design method is designed to optimize the above problems.

Embodiment 1

[0034] A method for designing a planar circuit diagram of a TCM element provided in this embodiment, such as figure 1 , including the following steps:

[0035] Step 1: Lock the design target of the application side: the voltage of the whole machine is 24V, the rated power is 60W, so the total resistance is limited to 9.6Ω. TCM appearance size is controlled at 308mm long and 220mm wide;

[0036] Step 2: According to the overall size of the TCM component 308*220, the epoxy edge banding is 5mm (not less than 4mm), and the design size of the locked base material is 298*210; according to the withstand voltage level requirements of the application end (24V DC), combined with the electrical design specification, Select the corresponding creepage distance to be 3mm (not less than 2mm), and electrical clearance to be 5mm (not less than 4mm); combine the existing TCM formula and the square resistance limit corresponding to the film thickness of 25-50Ω / □, the packaging material and proc...

Embodiment 2

[0071] In this example, if image 3 As shown, according to the design and application of the TCM component planar circuit diagram design method, two parallel TCM resistors are designed on the ceramic film in the direction of 308mm, and a series TCM resistor is formed in the direction of 220mm. The overall design power is 60W, and the overall target design TCM resistor It is 9.6 ohms. According to the parallel design of two TCM resistors, it can be deduced that a single conductive TCM should be 9.6*2=19.2 ohms. The designed single TCM resistor has a length of 131.5mm and a width of 178mm, so the square resistance R S =19.2*178 / 131.5=25.99.

[0072] 9 point temperature difference assessment

[0073] Adopt "YY / T 0061-2007 Specific Electromagnetic Wave Therapy Apparatus" Figure II The test points on the surface of the middle square heater (9-point distribution standard position) can be checked by applying the 220*308 area distribution. Except for the middle point on the silver ...

Embodiment 3

[0080] In this example, if Figure 4 As shown, according to the design method of the TCM component planar circuit diagram design method, three TCM resistors are connected in series in the direction of 308mm, and four TCM resistors are connected in series in the direction of 220mm;

[0081] The overall design power is 60W, and the deduced overall target design TCM resistance is 9.6 ohms. According to the deduction of the circuit diagram, the resistance value R1 of a single conductive TCM should be 9.6 / 3*4=12.8 ohms;

[0082] The designed single TCM resistor has a length of 43.25mm and a width of 82mm, so the square resistance R S =12.8*82 / 43.25=24.27.

Description

technical field [0001] The invention relates to a circuit diagram design, in particular to a method for designing a planar circuit diagram of a TCM element, and belongs to the technical field of circuit diagram design. Background technique [0002] Infrared is an electromagnetic wave with a wavelength between microwaves and visible light, with a wavelength between 760 nanometers and 1 millimeter. It is an invisible light with a wavelength longer than red light. Among them, the infrared rays with wavelengths of 700 nanometers-1.5 microns, 2 microns-4 microns and 8 microns-14 microns are extremely important to the survival of human beings and the growth of plants. They are called life light waves. The surface of the human body receives far infrared rays. It conducts and penetrates from the surface to the inside, and is absorbed to produce a warming effect, which resonates with tissue cells in the body and promotes cell activity. The warming effect can also expand blood vessels...
